Dear DK,
My experience with radiation was much different than your husbands since I had prostate cancer but the effects of my radiation were probably more directly related to sexual desire (libido) than radiation to the tonsils. When I was finished with my radiation treatments, which was 40 months ago, I had lost about 99 % of my libido and did not experience any erections for about 24 months. However with the absence of libido I didn't really care except for thinking that my wife might be feeling depressed or deprived. Now it appears something has changed down there. My libido is coming back, not like it was pre-treatment, but all of a sudden I'm starting to get spontaneous erections, mostly in the AM but often times during the day and seemingly for no reason at all since I wasn't thinking about sex in any manner. I don't know if this is normal or what causes it but I'm wondering if any other men have experience this change post radiation treatment. Bob
